What means "traffic share count" in "show ip route x.x.x.x" output

When I type a "show ip route x.x.x.x) I get following output:

Router1#sh ip route 10.232.30.25

Routing entry for 10.232.0.0/18

Known via "ospf 1", distance 110, metric 1594, type inter area

Redistributing via ospf 1

Last update from 10.205.106.109 on BRI1:1, 00:35:56 ago

Routing Descriptor Blocks:

* 10.205.106.109, from 10.205.104.2, 00:35:56 ago, via BRI1:1

Route metric is 1594, traffic share count is 1

I tried to understand the whole output but I can't find anything about the traffic share count parameter. The only thing a saw was: Number of uses for this routing descriptor block.

What does this mean exactely?

The traffic share count is used when you are load sharing across multiple paths (either equal or unequal cost). The counter indicates how much traffic (relatively speaking) will be placed on each link. If you were process switching, for instance, and had one path with a traffic share count of 1, and another with a traffic share count of 2, the router would place 1 packet on the first link, and 2 on the second link, then put 1 more on the first link, and then 2 more on the second, etc.
